1 Introduction 1.1. Intended Use The CVS-1 Vision Screener is intended to be used to measure the refractive power of the eye. It can measure refractive errors by detecting each eye from the eccentric lights. It is possible to measure in either binocular or monocular. The values from the measurements are compared with age based referral criteria. So, for some patient who need to visit a hospital, recommend as screening result. It is intended for use on subjects from 6 months to adults. 1.2.
